Hey KD...it's a no brainer...karate dudes that can kick butt and bald heads are like peanut butter and jelly...they were totally MADE for each other...Shave it bro! You'll love having a bald head!
Welcome to the world of the SLY karatedragon! You won't regret it if once you go SLY and if anyone should give you any grief...I'm sure you got the skills to deal with it.
